Chilton. — Notes on some New Zealand Crustacea. 129 



Munida gracilis Henderson. 



Munida gracilis Henderson. Ann. Mag. Nat. Hist., ser. 5, vol. 16. 

 p. 411, 1885; and "Challenger" Reports, vol. 27, p. 143, pi. 3. 

 fig. 6, 1888. 



Three imperfect specimens found in the stomach of a fish, Kaikoura. 

 These agree very closely with Henderson's descriptions, but they are 

 of much larger size. One of them, a female bearing eggs, has the follow- 

 ing dimensions : Length of body, 54 mm. ; breadth of carapace, 16 mm. ; 

 length of carapace, 19 mm. ; length of rostrum, 13 mm. ; length of cheli- 

 peds, 70 mm. 



Two specimens were taken by the " Challenger " at Station 166, west 

 of New Zealand, at a depth of 275 fathoms, but so far as I am aware the 

 species has not been seen since until the specimens now described were 

 handed over to me by Mr. Waite, Curator of the Canterbury Museum. 



Cryptodromia lateralis Gray. 



Cryptodromia lateralis Miers, Cat. N.Z. Crust., p. 57. 1876 ; G. M. 

 Thomson, Trans. N.Z. Inst,, vol. 31, p. 170^ pi. 20, fios. 1 and 2. 

 1898 ; Hutton, N.Z. Journ. Sci., vol. 1, p. 264, 1882. 



This species was recorded from New Zealand by Heller, and specimens 

 in the British Museum collections were referred to it with some doubt 

 by Miers when he was preparing the " Catalogue of the New Zealand 

 Crustacea." In 1882 Hutton included it in a list of species which had 

 been recorded from New Zealand, and might really belong to New Zea- 

 land, although at the time he wrote they were not represented in any 

 local collections known to him. This was still the case when Thomson 

 prepared his " Revision of the Crustacea Anomura," in 1897. Two or 

 three years ago, however, I received from Captain Bollons a specimen, 

 dredged in Hauraki Gulf at a depth of 22 fathoms, that undoubtedly 

 belongs to this species, so that, like soi.ie of the other species first re- 

 corded from New Zealand by Heller, and since considered doubtful, it is 

 found in New Zealand seas, though, apparently, only occasionallv. The 

 species is also known from Australia and Tasmania. 



Order Amphipoda. 

 Leucothoe traillii G. M. Thomson. 



Leucothoe traillii G. M. Thomson, Trans. N.Z. Inst,, vol. 14, p. 234, 

 pi. 18, fig. 1 a-d, 1882 ; Stebbing, Das Tierreich Amphip., p. 164, 

 1906. L. Widens, Stebbing, Rep. Voy. " Challenger," vol. 29, 

 p. 777, pi. 47, 1888 ; Chilton, Trans. N.Z. Inst., vol. 38, p. 268, 

 1905 ; Stebbing, Das Tierreich Amphip., p. 166, 1906. 



I have no doubt these two species should be combined. I had 

 identified specimens from Hauraki Gulf as L. tridens Stebbing, but T find 

 that they are the same as a Lyttelton specimen that I had years ago 

 referred to L. traillii G. M. Thomson, and I find from comparison of these 

 with named specimens of this species since received from Mr. Thomson 

 that no difference can be detected between them. Mr. Thomson de- 

 scribes the dactyl of the first gnathopod as being " finely serrated on its 

 inner margin," but in all my specimens it appears quite smooth. In Mr. 

 Thomson's mounted specimen the dactyl lies close up against the propod,
